FIELD: transportation, submarines. SUBSTANCE: device for ventilation of wrecked submarine compartments from the rescue ship, incorporates a compressed air feed hose and a contaminated air venting hose, both being jointed by threadless joints to the wrecked submarine compartment vent valves. The said vent hoses are jointed, at the ship, to a receiver with an water-gas ejector attached to the said receiver and creating rarefaction therein, driven by the operating fire-pump. EFFECT: higher-efficiency air exchange in wrecked submarine. 1 dwg
The invention relates to a rescue technique, namely, devices intended for ventilation of compartments emergency submarine (SSN), lying on the ground, to sustain personnel to his rescue. It is now known device ventilation PL a two-step consists of two hoses exhaust contaminated air from the compartments of the submarine with a two-step slip riser and one sleeve compressed air fittings for connection to the valves ventilation APL /1/. A significant disadvantage of this device is its low efficiency, characterized by low flow discharge from the compartments of ALL air due to the limited pressure differential between the compartment and the atmosphere of 0.1 MPa (1.0 kgf/cm2), and small total cross-section of the discharge hose. This disadvantage reduces time and life support personnel located in the compartments emergency submarine. The objective of the invention is to increase the efficiency of the ventilation device by increasing the flow outlet from the compartment of the submarine air by increasing the pressure differential between the compartment of the submarine and the atmosphere. This task is achieved by the fact that the hoses exhaust on the rescue vessel connected to the receiver, in which the om creates negative pressure (vacuum) in the suction of the air through the water-gas ejector. Figure 1 shows the device ventilation, General view, figure 2 receiver with the water-gas ejector, cut. The ventilation device includes a sleeve compressed air supply 1 connected with non-threaded connection to the valve receiving compressed air 2 strong body NPS 3 and the hose drain 8 with a discharge line connected with a strut with non-threaded connection to the valve air outlet 9. The sleeve 1 and the hose 8 served with rescue vessel along the guide ropes respectively 4 and 11, fixed to the body of the submarine and on deck. To the valve air outlet 9 in the compartment of the submarine is connected to the hose 10 for sampling contaminated denser air from the bottom of the compartment. Fresh compressed air through the valve 2 is fed into an upper compartment of the submarine. Valve 2 and 9 have dual control drives with partitions "Epron" in the add-in and out of the compartment of the submarine. Clean compressed air into the sleeve 1 is fed from the storage of high pressure air or from a compressor of the rescue ship on the pipeline 5 with shut-off valve 6 and a pressure gauge 7. The upper ends of the hoses air outlet 8 is connected to the receiver 12 with the water-gas ejector 13 and 14 gauge. Working water under pressure to the nozzle 15 of the ejector 13 is supplied by pipeline 16 with shut-off valve 17 and a pressure gauge 18 from the fire pump 19. The receiver 12 with the water-gas ejector westhoven on the frame 20, mounted on the deck of a ship. The ventilation device operates as follows. On command from the rescue vessel personnel in the compartment ZPL slowly turn opens valve 2 and exhaust air 9 to drain the remaining water from the hose 1 and hose 8. If the compartment ZPL had high blood pressure, then the decision on the need for its reduction through the outlet hose 8 to a normal pressure by a special mode of decompression. After this opening of the valve 6 into the compartment ZPL is served clean compressed air to a pressure of 0.1 MPa (1.0 kgf/cm2) - redundant. Opening of the valve 17 through the pipe 16 from the fire pump 19 is supplied working water pressure of 0.5-1.0 MPa (5.0 to 10 kgf/cm2in the nozzle 15 water-gas ejector 13. As a result of work-water ejector 13 from the receiver 12 is pumped out the air and it creates negative pressure (vacuum). Thus, while maintaining the required pressure in the compartment of the submarine through the supply of clean compressed air from the rescue ship on the sleeve feed and create the maximum possible dilution of the discharge air in the receiver due to the work of water-gas ejector increase of the pressure difference between the compartments of nuclear submarines and the atmosphere, which causes the increase of the flow rate of the discharge of polluted air Creating devices ventilate the compartments of nuclear submarines, equipped with a receiver with a water-gas ejector that generates a negative pressure at the end of Platov-of-way, will improve the effectiveness of the ventilation of the compartments of nuclear submarines, to ensure a long maintenance personnel, and therefore his salvation. The source of information 1. The ventilation square THE two-step S-75 The device ventilation of compartments emergency submarine lying on the ground, from the rescue vessel containing the sleeve compressed fresh air and hoses exhaust contaminated air, is connected using the non-threaded connection to the valve ventilation of compartments emergency submarine, characterized in that the hose exhaust air on the rescue vessel is connected with a receiver attached to it and creating it underpressure (vacuum) water-gas ejector operating at the flow of water from the fire pump.
